1. Signal detection and probability discrimination using maximum likelihood ratio method with Python implementation. 2. Bayesian detection method for signal analysis with statistical modeling. 3. Risk coefficient evaluation in classification decisions with mathematical formulation.
This program implements wavelet transform for online monitoring of power systems. Detection signals in power system monitoring often contain substantial background noise, making analysis challenging. The wavelet transform approach effectively addresses this issue. The implementation uses db3 wavelet for 5-level decomposition, producing detailed and approximation signals at each level through a multi-resolution analysis framework.
